Okay so this took some time but
you need 1 more cup.
in each cookie there is 1/9th of a cup so to make 45 cookies you need 1 more cup. WE COULD BE COMPLETELY WRONG
Answer:
x = 45/17
Step-by-step explanation:
We can move all x to 1 side and all the numbers to another. You can add 8.7 on both sides and get that 2.3x = 0.8x + 4.5. Next, we subtract by 0.8x on both sides to get that 1.7x = 4.5, where we can then divide by 17/10 on both sides to get that x is equal to 45/10 * 10/17, so that means that x = 45/17.
The steps are shown here.
1) Factoring
2) Completing the square
3) Quadratic Formula
4) Graphing
So basically the answer would either be 5 or -5.
